NGK - NGK Iridium IX Spark Plugs for LSJ #

What do you guys think of these plugs?
Was thinking of getting them. I emailed ZZP asking what plugs they reccomend for my setup/tune. But wanted some other opinions. I figured if ZZP sells them they must be good.


My current set up
2006 SS/SC
2.9" Pulley
Dual Pass Endplate
Pheonalic Spacer
OTTP stg1 HE
60# injectors
ZZP 3" Intake
ZZP Long Tube header W/ Catted downpipe

I'm currently running NGK Coppercores at 1 step cooler.

Iridium plugs on a LSJ are hit or miss. Some cars like them, some don't. Most like copper though.
